听力原文：W: How do you go to work every day, by bike or by bus? M: By bike, of course. W: Why don't you take the bus? Obviously it can save much time and energy. M: I find it hard to agree with you. Sometimes if the bus is stuck in a traffic jam, it will waste much time instead of saving it. W: Maybe you are right, but what if it was raining or storming? Will you still ride on your bicycle to your office? M: Well, it all depends. If time permits, I will keep my habit and go to work by bike. But if time is pressing, I may choose the bus-ride, which is the last thing I'd like to do. W: I can't make out why you hate the bus-fide so much. M: Well, indeed, what bothers me the most is not the occasional traffic jam as I mentioned before, but the rode people with their rough behavior. on the bus. W: I don't get it. M: Every time I have to go to work by bus, it turns out to be a terrible experience. If worse comes to worst, you may find yourself on an overcrowded bus with no order, and in a near-riot. I'm not exaggerating. W: I see what you mean. I'm sorry for you. M: During rush hours you have to fight your way in, and fight your way out when you get off. W: How terrible! M: By the way, how do you go to work? I'm curious. W: Well, I have a car of my own, so I neither take the bus nor ride the bike. M: No wonder! (20)
